Mounting for eyeglasses.



UNITED STATES PATENT orrion.

Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed October 27, 1905. Serial No. 284,720.

To all whom, it may concern.-

Be it known that I, HARRY A. SEIDEL, a citizen of the United States,residing at Lebanon, in the county of Lebanon and State of Pennsylvania,have invented certain new and useful Improvements in Mountings forEyeglasses; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to mountings for eyeglasses, has for its object amounting in which the bridge or spring and the guards are integral, andconsists in certain improvements in construction, which will be fullydisclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a front elevation of a pair of eyeglasses providedwith my improved mounting; Fig. 2, an inverted plan view of the same;Fig. 3, a perspective of the mounting detached and on an enlarged scale,and Fig. 4 an elevation or plan view of one of the guards detached.

Reference being had to the drawings and the designating charactersthereon, the numeral 1 indicates the bridge or spring, usuallydesignated as the bow or bridge-piece. In the present instance itconsists of a normally straight or horizontal round rod bent downward at2 2 at each end to a'lford tension to the spring to cause the guards 3 3to grip and securely hold the glasses on the nose of the wearer.

4 4 indicate another bend in each end of the spring, the bend beingupward and opposite or substantially at right angle to the bond 2, whichaugment the tension of the mounting, and as the glasses or lenses 5 areseparated or pulled apart the upper ends of the guards approach eachother, and thereby tighten or increase their grip on the nose.

From the bends 4 4 the bridge or spring extends upward at 6-6 andterminates in the guards 3 3, which in form or contour resemble theletter C, are provided with ridges 7 011 their inner surfaces, inwardprojections or protuberances 8 8, which are embedded in the flesh of thenose by the tension of the spring and in conjunction with the opening 99 in the guards, which is filled with the flesh of the wearer, securelyhold the eyeglasses in position and prevent their being accidentally vdisplaced on the nose.

The guards 3 3 are formed by displacing the metal in a suitable die andforming an inwardly projecting flange 9, which increases theirbearing-surface, and are provided at their ends with lugs 10 10, towhich the posts 11 11, engaging the lenses, are secured by screws 12 12,and are so located by being bent back or outward that the screws cannotcome in contact with the nose.

The guards are slightly concavo-convex, which increases their grippingpower and assists in holding the glasses in position.

The bridge or spring and the guards bein made in one continuous piece ofmetal greatly reduces the liability of the mounting becomingloose by thewear and tear upon the screws, as in mountings in which the spring andthe guards are separate and secured by screws.

The mounting is preferably made by the use of formers or dies forbending the bridge or spring at its ends after the guards have beenformed in a suitable male and female die; but it is obvious that thebending of the spring may be done by hand with suitable pliersconstructed for the purpose.

Having thus fully described my invention, what I claim is- 1. Aneyeglass mounting comprising a bridge or spring having guards formedintegral therewith on the ends thereof, said guards having an open ngtherein and pro vided with laterally-extending flanges, and lugs on thefree ends of the guards for attaching posts thereto.

2. An eyeglass mounting comprising a bridge or spring having guardsformed integral therewith on the ends thereof, said guards having anopening therein and provided with inwardly-extending flanges, andprotuberances, and lugs for attaching posts thereto.

3. An eyeglass-mounting comprising a rodlike bridge or spring havingintegral guards at the ends thereof provided with an opening, andlaterally extending flanges bounding part of the opening, and lugs forattaching posts thereto.

4. An eyeglass mounting comprising a mately O-shaped, and provided with"iater- IO bridge or spring having bends at the ends ally-extendingflanges, and lugs. thereof and terminating in open guards inte- Intestimony whereof I affix my signature gral therewith and havinginwardly-extendin presence of two Witnesses. 5 mg flanges, and lugs atthe ends of the guards.
